With less than a week to go, the newly svelte songstress’ team was shopping over the past few days for a gig paying up to $500,000 at any venue in the United States and beyond.

We’re told that Carey’s team also was asking for a private jet to fly her and her entourage out of Aspen, where she’s spending the holidays with her family.

A source told us: “Mariah’s management was looking for a very lucrative deal for her, but she’d sing only just a few songs. But there haven’t yet been any takers.”

It is not clear whether Carey’s hubby, Nick Cannon, would come as part of the package.

The source added, “While her team is fielding her offers, Mariah is happy spending the holidays with her twins and husband.”

A rep for Carey denied the superstar had been actively looking for a deal, saying: “She’s not doing any New Year events. She’ll be in Aspen with her family.”

Stars raking in big bucks to ring in 2012 include superstar DJ Tiësto, who has a multimillion-dollar deal with Vegas casino king Steve Wynn and will play at Haze at the Aria Hotel & Resort on Dec. 31 and other dates.

Also in Las Vegas, Black Eyed Pea Fergie is earning about $100,000 for playing the new 1Oak at the Mirage Hotel and Casino.

Kim Kardashian will appear at Tao in Sin City as part of a larger deal worth up to $600,000 for multiple appearances.

Sean “Diddy” Combs had been in talks to perform at the opening of Hyde in Vegas but backed out of the deal and is throwing a private bash at his home on Miami’s Star Island.

Katy Perry had also been asking for $250,000 for an Eve appearance, but with no performance. We’re told there were big offers thrown at Ashton Kutcher, but he declined them all.

Meanwhile, DJArmin van Buuren will spin for $250,000 at Dubai’s World Trade Centre.
